Abstract: FAILOVER ISSUES: SSA CLUSTER ADAPTER AND HOST SW 1.06, 1.07


SYMPTOM:

Microsoft Cluster Server (MSCS) Failover will hang and will not complete.


PROBLEM ISOLATION AIDS:


FIX:

Fix will be implemented in a future revision of the driver and adapter firmware.


WORKAROUND:

Use Windows NT SP 3 and the 1.05 driver package, which ships with the SSA RAID Cluster Adapter.

The 1.05 package is also available at:

http://www.hursley.ibm.com/~ssa/pcserver

Note: There is no workaround with NT SP4 until the new driver and firmware is released.


DETAILS:

An issue with SSA driver package versions 1.06 and 1.07 causes problems when used with Microsoft Cluster Server.
In this environment, MSCS failover will hang and will not complete.

Operation in a non-clustered (one-way) environment is unaffected.
Because SP4 is required for the SerialRAID Adapter (Option 09L2084/7133 Feature Code 4013) and Advanced SerialRAID/X Adapter (Option 09L2123 / 7133 Feature Code 4040), use of the SSA RAID Cluster Adapter in the same system as either the SerialRAID Adapter or Advanced SerialRAID/X Adapter is unsupported when used in conjunction with Microsoft Cluster Server.
